Double side grinding

ELID-side grinding (Zhang et al., 2000, 2001a) ELID double-side grinding (Ohmori et al., 1996)... 

ELID double-side grinding can be employed to produce mirror-like surface finish. 

The material removal mechanism for ELID double-side grinding was brittle-fracture mode for coarser wheels and ductile mode for finer wheels. 

The material removal rate for ELID double-side grinding was slightly higher as compared to conventional grinding. 

ELID double-side grinding setup is presented in Figure 9.14. A close-up view of the same is given in Figure 9.15. The conclusions of the study were presented in the following list ...

Double Side Grinding of Advanced Ceramics with Diamond Wheels... 

ABSTRACT A double side grinding (DSG) computerized kinematical model accoimting for piece rotation inside its slot into the carrier was developed. Trajectories for representative points located on the end faces of the workpiece were simulated. A radial wear gradient of the active surface of the wheel was predicted. Experiments accomplished with different wheel specifications, process parameters, operation duration, and coolant types were carried out. A strong correlation was foimd between the predicted length of the trajectory of a specific point located on the piece surface and the experimental material removal rate. A radial wear gradient was experimentally confirmed. Conclusions on optimizing the DSG process for advanced ceramics with diamond were drawn.
